    Fiber-Reinforced Concrete

    For reduced crack widths

    What is fiber-reinforced concrete?

    Fiber-reinforced concrete enhances the durability of concrete by reducing crack widths typically due to plastic shrinkage, long-term drying shrinkage and thermal changes. Because concrete cannot be prevented from cracking, the goal is to keep the cracks tightly closed. 

    Benefits that can be achieved with fiber-reinforced concrete include extended service life with reduced maintenance, faster speed of construction, labor savings and improved worker safety.

    Microfiber vs. Macrofiber

    • Microfibers: Less than 580 denier or .30 mm. Used in concrete where extra toughness is needed, evaporation rate is high and surface appearance is important. Microfibers are not a structural reinforcing fiber and cannot be used to replace any structural steel elements.
    • Macrofibers: 580 denier or 0.30 mm or greater. Used for plastic shrinkage control (cracking that can occur in the first 24 hours of concrete cure), impact protection and fire anti-spalling.

    Concrete Fiber Additive Products

    • Master Builders Solutions offers a range of concrete fiber additive products, including:
    • Monofilament microfibers for control of plastic shrinkage cracking
    • Fibrillated microfibers for replacement of light-gauge welded-wire reinforcement
    • Macrofibers for post-crack control and replacement of traditional shrinkage and temperature (secondary) reinforcing steel
